I don't really have SE Vivaz but I'm a Symbian S60 V5 lover which makes us even here... After reading lots of comments here, I thought I better give you a list of applications (Must have applications) in your Vivaz (Symbian S60V5)

1) Google Maps (Just like Google earth on your PC)

2) Y-Browser (File manager software, but way better than the default one... You can go in to hidden system files too)

There are many many more... I just named MUST have applications... There are no games in above list... You can have hundreds of nice games and funny applications apart from above list...

HOWEVER....

You should sign above applications before installing... (You can use 'Free Signer' applications for that..) Or else you must have a hacked phone... (I don't know whether SE Vivaz can be hacked or not.. You have to google for more information)

You can download almost all the above applications from www.dotsis.com (Of course cracked versions...)

I'm actually using Nokia 5530 Xpress Music which has the same OS as this... and I have all the above applications installed in my beauty... So I can say with confidence... Symbian ROCKS...!

My girlfriend got me some Sennheiser MM50 headphones, the pack said they are iPhone compatable but I own the Vivaz... I tried them as they have the same jack but they fail, I tested them with my PSP and they work great with that, I then tried it in my girfriends HTC HD2 and they worked 100%.

My vivaz comes up with the option to select headset or TV out when I plug the headset in but after selecting the headset option I get nothing through the headphones for music or calls. (TV out just gives me white noise with teh music as background)

Are they non compatable or have I missed something obvious? if I can't get the things working I will just use them with the PSP or give them back to my girlfriend as they seem to work fine for her...

so dear friend can you help me do this things?
i dont have it yet i want to get my cer and key.can you help me to do it?
but what about this Symbian sis signer(if thats the name), is this an online signer..?

yes that's so possible.
only if you install a 3rd party application.
there are different apps that has the ability to hide your files (for example private photos, videos such as porn). :D.
One of which is the 'file lock' as our friend Fatos have mentioned.
(be sure to read the comments before you install the appslication, for you to be sure that it is safe to install)

i believe our friend Fatos has already provided the link where to get Media Safe application.

to be honest, i havent tried an android phone so i cant be particular in answering this question. but as far as i know yes android has more application already preloaded to the phone. but with symbian we can also achieve such apps thru 3rd party apps

yes, there are several apps that need a huge amt of RAm to run smoothly, same thing when running several applications in the back ground. this slows your phone's performance. it causes lags as well or worst when you dont have enough Ram to run an application it sometimes restarts.

one good solution is to monitor your ram usage. close an application when not in use and dont forget to restart your phone at least once in two weeks.
vivaz is a very good phone. that's one good reason to take good care of it.

Played a song on my Vivaz last night. Didnt switch the phone off, but left it beside my bed. This morning when I tried to listen to music on my way to work I noticed that the music option in the media player is gone. Only photos and videos options are still there. I've checked the file manager and all the music files are still on my memory card.

So, has anyone else experienced this problem and how do I fix it? While a simple software upgrade do the trick?

1.about your first question,No its not necessary to sign all apps or games,because some apps are already signed weither by the company who has launch it or by other persons,but some files as you said they need to be sign
2. abot second and third question I see they are connected....My friend I personally use this Symbian sis signer and its very good,you can find here and download it http://www.mobilesbuddy.com/mobile-software/noki­a-s60v5-software/symbian-sis-signer-software/
But remember befor using sis signer you must have certificate and key for your phone,whithout those you cant sign sis files,If you have it good,and if you dont i will guide you how to get it.
3. and fourth question,the best way to find cool apps and games is google,you can find HD games for you phone,and check youtube its very useful
And thank you again Gillian,and you are so useful in GsmArena,I can see it....
